Correspondingly it activated.
It can be taken measures according to the present invention herein, the control is made also to utilize other criterion in other cases.It may
Other criterion be listed below：
Radius, depend on decrescence, it is cumulative, stepping, have it is arbitrary desired it is contemplated that transfer function；
Gait of march or transverse acceleration；
Tractive force (is determined) by measuring the longitudinal movement between car body 110 and chassis 100；
Actuator force itself (determined by the pressure measurement in actuator 1, wherein this consider wheel with track it
Between contact geometry shape quality)；
The independent control (first side or caudal) of wheel pair；And
The control of higher frequency range, to stablize chassis (almost in the level segment of sinusoidal motion), so as to omit
The use of stabilizer.
In addition it can take measures, it includes pump to make hydraulic pressure unit 13, and motor is made only to start when needed.More than expectation/reality
When the second threshold of border position difference, pump can start, and the energy expenditure of actuator can be thus substantially reduced.It means that pump
Actually it need to only be opened under the conditions of the track with bad contact geometry shape, and taking turns makes to 50 from not additional force
In the case of with acceptable contact geometry shape to correct position because this is not also only utilizing hydraulic pressure list by passive trigger valve
It is feasible in the case of member 13.

Information.System delay when pumping up dynamic of the hydraulic pressure unit of caudal chassis can thus be eliminated and excluded in due course.Thus
It can also optimize for running the control method for passing through easement curve or switching for track.
Actuator is preferably automatically controlled by each chassis.Energy supply device is only needed, and at data snooping, data
Reason and its actuating then carry out in chassis.
Wheel is preferably integral in arbor guide portion bearing or spring bearing the actuator 1 in guide portion at this.Motor,
Pump (the two is indicated with reference numeral 13), valve 11, path sensor and pressure sensor and control unit are arranged to control figure
Actuator 1 in 8.Other sensors needed for higher level control method are not excluded the presence of.Herein it is contemplated that such as acceleration
Meter or gyroscope.Advantageously, external hydraulic circuit is not present, thus leakage or failure risk are substantially reduced.
The control of actuator 1 is faulty protection in design, this is because system is used as rigid wheel to guide portion,
When electronic component, sensing system, power supply, pump and/or motor break down with high inherent damping.It means that institute
It states chassis to work similar to traditional bottom bracket, without taking turns to controlling or with the extremely control of effect slowly.
In leakage or longitudinal Hardness loss, chassis takes operation of jolting, and can lead to irregular operation.But, in system
Remaining damping and residual hardness to prevent wheel rail force be more than safety-related limiting value.
According to a preferred embodiment of the invention, it can in addition take measures, energy is made independently to supply.Power generating unit is set
It sets for this purpose, its energy is generated using the pressure change in synchronized cylinder.For example, the hydraulic fluid extruded outside cylinder also can be herein
For generating energy.In straight forward, the pressure in cylinder also continuously changes so that the actuator of passive connection also is used as energy
Amount source.The power supply of the electronic component of sensing system, valve and pump can be ensured by this energy.Energy generates herein
It can be maximized by directly activating the valve under different travel conditions.
Advantageously, the control of autonomous energy supply modification actuator 1 in this way is imagined.This imagination, which can also be worked as, to be needed
Energy hole state that will be especially low and while being not necessarily limited by autonomous energy supply uses.
In this regard, 1 independent actuation of each actuator, wherein each valve only allows oil quasi- towards actuator along desired orientation
The position flowing taken.If the contact geometry shape between wheel and track is enough, wheel to also can ideally due to
This control is individually used.But, actuator is made independently to be adjusted to the phase if the quality of contact geometry shape is not enough to reach
Hope position, then advantageously, two cylinders of first side and caudal wheel pair are coupled to each other via underground and additional valve so that
The hydraulic fluid stream of caudal wheel pair can be used to control first side wheel pair as needed.
This embodiment is paid special attention to due to lacking free space without allowing turning over for the relatively old vehicle for installing energy supply device
Newly.Controllable actuator is because without any hydraulic pressure unit for including motor and pump, but only valve is arranged in synchronized cylinder
Between each separate chamber.In this way, only the cylinder can be made to generate power indirectly or passively.This is for example carried out in the following manner：
